On a corrugating line, the belts are easy to forget – until one fails and the whole line stops. A little attention to selection and daily care keeps them running much longer.
Two kinds of belts we supply
Corrugated (corrugator) belts
Corrugated belts carry and press the board through the double facer, where heat and pressure bond the liners to the fluting. They must transmit heat evenly, release moisture and stay flat under load.
Conveyor belts
Conveyor belts move reels, sheets and finished boxes through mills and converting plants. They must grip, track straight and resist wear.
What shortens belt life
- Poor tracking – the belt runs to one side and wears edges.
- Wrong tension – too tight stretches the belt and bearings; too loose causes slipping.
- Dirty belts – starch, glue and dust build up and harden.
- Damaged rolls – worn or misaligned rollers cut and mark the belt.
- Wrong belt for the job – weight, width or permeability that does not suit the machine.
Daily and weekly care
- Check tracking at start-up and after every stop.
- Keep tension within the manufacturer’s range.
- Clean glue and starch build-up with suitable methods – never sharp tools.
- Inspect seams and edges weekly.
- Keep rolls aligned and bearings greased.
Signs it is time to replace
- Edge fraying or cracks.
- Uneven board quality – warp, poor bonding or marks.
- Seam failures or visible damage.
- Frequent tracking problems that adjustments do not fix.
